Overall size is about 20 in diameter by 9.8 in high, and it weighs 7 kg (15.4 lb.) for planning your mounting surface and pedestal.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e4 kW peak output with 36 nm max range and 20 m minimum range.\u003c\/li\u003e\n\u003cli\u003eX-band radar (9.38 to 9.44 GHz) in an 18 in dome for installations where an open array is not practical.\u003c\/li\u003e\n\u003cli\u003ePower input 11 to 32 V DC with a 7.5 A fuse; typical draw is 15 W in standby and 40 W while transmitting.\u003c\/li\u003e\n\u003cli\u003e24 RPM dome drive for consistent updates with low-noise operation.\u003c\/li\u003e\n\u003cli\u003eDynamic auto gain and dynamic sea filter to keep the picture readable as sea clutter changes.\u003c\/li\u003e\n\u003cli\u003eRadar overlay and MARPA target tracking supported on compatible setups; MARPA requires a heading sensor.\u003c\/li\u003e\n\u003cli\u003eNetwork integration supports Garmin BlueNet and Garmin Marine Network installations (an adapter cable may be needed depending on the network hardware).\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis scanner is controlled from a compatible Garmin chartplotter over the Garmin marine network, so plan for an available network port (or a network switch\/port expander) at the helm. If you want MARPA target tracking, a heading sensor is required, and a heading source also helps radar overlay line up cleanly on the chart.\u003c\/p\u003e\u003cp\u003eFor layout on board, the compass-safe distance is 1.2 m (3.9 ft.), which matters on sailboats and smaller pilothouses where the dome and compass can end up close together. Confirm you have overhead clearance for the 20 in diameter dome and space below the mounting surface for cable routing and bend radius.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eMount the dome on a flat surface that sits parallel to the vessel waterline and can support the load underway. On a hardtop or cabin roof, a pedestal can help keep the radar beam clear of the roof edge, especially on boats that run with a higher bow angle.\u003c\/p\u003e\u003cp\u003eUse the supplied mounting template, seal all fastener holes and deck penetrations with marine sealant, and secure the cable run so it is protected from chafe and sharp bends. Keep power and network cables away from high-heat sources and avoid running them parallel to other high-current wiring when possible.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eRun the power cable as close to the battery source as practical and keep connections clean and dry, especially in saltwater environments. If the power cable needs to be extended, use wire gauge appropriate for the added length so the radar still sees stable voltage while transmitting.\u003c\/p\u003e\u003cp\u003eBefore first power-up, confirm the in-line fuse is installed and that your distribution panel and battery bank can support the load during transmit periods, particularly on boats that spend long stretches at anchor.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis dome radar is a strong match for center consoles, cruisers, and cruising sailboats that want networked radar on a Garmin chartplotter without committing to an open array. It is most useful for early-morning runs, foggy approaches, night entries, and anytime you want another layer of awareness around traffic and weather.\u003c\/p\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eGMR 18 HD3 dome radar\u003c\/li\u003e\n\u003cli\u003ePower cable (15 m)\u003c\/li\u003e\n\u003cli\u003eNetwork cable (15 m)\u003c\/li\u003e\n\u003cli\u003eMounting hardware kit and mounting template\u003c\/li\u003e\n\u003cli\u003eInstallation instructions\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":52269485293749,"sku":"QBP488028","price":1799.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1300124_qbp488028.jpg?v=1771544234","url":"https:\/\/www.qualityboatparts.com\/products\/qbp488028","provider":"Quality Boat Parts","version":"1.0","type":"link"}
